The electrical nominal values are within a range of ± 3
percent of the stated values of I

, U

and P
max
under
standard test conditions (radiation density of 1,000
W/m², AM 1.5 spectrums and a cell temperature of
25 °C) in the sense of the tolerances of the measuring
instruments used.
In normal outdoor use conditions, the current strength
and voltage produced by the module deviate from the
values stated on the datasheet. The datasheet values
are the values achieved under standard test condi-
tions. The short circuit current values and the open
circuit voltage values should be correspondingly multi-
plied by a factor of 1.25 during system design in order
to be able to sufficiently size the component voltage,
current load capacity of the conductors, size of the
fuses and size of the regulating devices connected to
the modules or to the system output.
The open circuit voltage of the PV system must not
exceed the maximum permissible input voltage of the
inverter used and the maximum system voltage acc.
to the module datasheet (1,000 V). The maximum
system voltage of other system components must also
be observed.
Do not use modules with different configurations in
the same system.

The cross-sectional area of the cable and the con-
nection capacity must correspond with the highest
short circuit current of the system (the recommended
cross-sectional area of the cable is 4 mm² for a single
module, nominal current of a connection > 10 A), as
otherwise the cable and the connection over heat at
high current strength.
The modules fulfil the requirements of application
class A (IEC 61730), protection class II.
